On theStimulated BrillouinScattering Effect of Electrically Band-limitedCSRZ SignalinOptical Transmission

We demonstrate thenewlyproposed electrically band-limited CSRZ (EB-CSRZ)signal generator witha wideband CMOS signal mixer. Thesignal mixerisfabricated with0.13-pm CMOS technology andconsists ofinverter stages fordataandclock signals, amixing stage forswitching dataand clocksignals, and a differential amplifier foradditional amplification. The implemented signalmixerhas 3-dB bandwidth of6.4GHzandisolation between dataandclock of21 dBat3-dBbandwidth. TheEB-CSRZwiththesignal mixerhas beendemonstrated up to10Gb/s.Thestimulated Brillouin scattering threshold oftheEB-CSRZsignal isabout+12dBm.
